Abstract

Disclosed are aircraft airframes (20) for providing reduced fuel burn, weight and cost. A fuselage (22) accepts a single gas generator core (38) configured to remotely drive multiple, bladed propulsion elements (36). The propulsion elements (36) may be fans or propellers. An outer cowling (34), extends radially outwardly from the fuselage (22), accepts an ambient air stream (50), and accommodates the bladed propulsion elements (36). The bladed propulsion elements (36) discharge the ambient air stream (50) rearward as a bypass stream (52) portion and a core stream (54) portion. An inlet duct (86) directs the core stream (54) portion into the core (38).
